To all whom it may concern:

Be it .known that T, GEORGE W. STEIN, a citizen of the United States, residing at Chicago, in the county of Cook and State of llllinois, have invented certain new and useful Improvements in Combined Window Ventilators and Screens, of which thefollowingis a specification.

This invention relates 'toventilators for windows.

The object of the-invention is to provide a ventilator of this "character so constructed as to be used for both top andbottom window sash and on either the inside or the outside thereof or both, and alsoas a screen.

. Another object is to construct ventilators of this character which will seat snugly against the window sash to pro vide for the opening of either, the top or bottom sash or both without danger of dust and insects entering between the ventilator and the sash. Another object is to. provide a protector and ventilator for the center of the window to prevent the entrance .of dust. and insects when either sash is opened.

With the foregoing and other objects in view, which will appear as the description prbceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the inventlon herein described may be made within the scope of-what is claimed withoutdeparting from the spirit of the invention.

struction is shown including'the usual frame F with the upper and lower sash S and d mounted to slide therein in the usual manner and which may be held in raised or low- 6t ered position by any suitable means.

In Fig. 1 the window W is shown equipped with ventilators constructed in ac-' cordance with this invention applied to both the upper and lower sash at their top and bottom, respectively, and to the center of the a window where the sash rails of the upper and lower sash 'meet; These ventilators ma be of any desired pattern, the bottom ventilator 1 and the intermediate ventilator 20 being here shown of the same pattern, while the top ventilator 30 is of a difl'erent pat tern, the structure of all being the same.

The ventilator 1 which is shown mounted on the inside of the window at the bottom thereof is composed of two sheets of material 2 and 3, which may be of card-board, thin sheet metal or any other thin material. These sheets are made of the same width and length and are each provided with a shown at l which may be of any desire confi ration, the openings in the two plates filling preferably arranged to register with'each other and permit the passage of air through a foraminous member 5 whichis positioned between these plates and secured in any suitable manner, preferably bystitching, although obviously any other means may be employed for this-purpose. This fabric 5 may be of cheese cloth, or any loosely woven fabric and fine mesh wire is sometimes found and when fitted to a window are measured f ed in lengths corresponding to the distance between the strips 8 carried by the inner faces of the side members of the frame.

After being so measured they are-cut transversely an the endsthereof are preferably finished by metal strips such as those shown atfl' in Fig. .7, although these strips need not necessarily be employed. Carried by the side strips 8 at each side of the f zajme are ventilator guides 7 shown in detail'inf These guides are constructed of sheet metal plates folded lon 'tudinally to provide inner and outer mem ers 8 and 9 which arespaced laterally apart a suficient distance for the )passage between them of the ends of the ventilator strips, said folded 'plates being bent at right angles to each its upper end with a pliable lug or finger 11 which is adapted to be bent downwardly over strip 1 after the ends thereof have been inserted between the plates 8 and 9 thereby securely clamping the strip in operative engagement with the guides as is shown clearly in Fig. 1.

In applying this ventilator, the guides 7 are first positioned on the sidestrips s in close proximity to the lowersash S and are secured to said side strips by fastening screws which are passed through the aper tures 10in the guides. The ventilator strip 1 is .then inserted in said guides and the pliable fingers or lugs 11 bent downwardly over its upper edge. When so positioned the strip 1 which is of very thin construction will lie close against the inner face of the lower sash and thus effectively operate to prevent the entrance of dust between the sash and the ventilator when the sash is raised, it being understood that the sash is never raised above the upper edge of strip 1 except under extraordinary conditions, that is, when a person desires to lean out of a window or for some other urpose.

The foraminous fabric 5 w ich is clamped between plates 2 and 3 may be of any desired color and preferably matches the shades used,although obviously if desired it may be made to match the painting of the window frame to which it is a plled. While this bottom ventilating member 1 is here shown a plied to the inner face ofthe window, it o viously maybe equally well used on the outer face of the window, the window then sliding against the inner face of the ventilator strip instead of against its outer face.

This strip 1 is provided along its lower edge with a laterally extending flange 12 which. is designed to fit snugly against the upper face 0 the window sill s as shown in Fig. 4 and to be secured thereto by tacks or other suitable fastening elements which may be readily removed when it is desired to change the pattern of the ventilator or to provide a new one for any reason.

The ventilator 30 which is disposed at the top of the window frame is constructed exactly like the lower ventilator 1 except that the openings 35 therein are of a different, configuration from those shown in the ventilator l and the flange 31 thereof instead of being on the lower edge of strip 30 is on its upper edge and is of course secured to the inner face of the upper portion of frame -1 as is shown clearly in Fig. 2, said flange bein secured to said frame by tacks or other fastening elements. The ventilator guides 37 arranged at opposite sides of the frame are exactly the same in construction as those shown at the lower end of the frame, except that they are arranged in reverse position so that the fingers 32 are disposed downwardly and are bent upwardly around the lower edge of the ventilator strip to hold it in engagement with the guides.

8 In F 1g. 2, two of these ventilators are 0 shown, one being arranged on the inner side of the window and the other on the outer side. When used on the inner side of the window the plates 33 and 34 between danger of insects entering between the ventilator and the sash is obviated.

The intermediate ventilator 20 shown in Fig. 1 is designed to be mounted in guides mo 21 which here constitute a portion of the sash locking devices, although obviously they need not necessarily be so formed. These guides 21 have laterally extendlngl fingers 22 between which the ventilator ends are designed to be inserted. As shown in Fig. 3, this ventilator 20 is carried by the lower rail R of the upper sash S, being proa' vided with a laterally extendin flange 23' which is fastened to the sash rail by tacks 11 or other suitable fastening elements. It

will thus be seen that when the upper sash is lowered or the lower sash raised this ventilator 20 will operate to effectively close the space between the two sashes and prevent all possibility of dust, dirt or insects entering at this point.

In the form shown in Fig. 6 an extensible ventilator 50 is illustrated, being composed of two telescopically engaged sections 51 20 and 52 which slide longitudinally on each other in overlapping relation, one being provided with inturnedears 53 and the other with similar cars 54 which form guides for the two sections in their move- 12g ment toward and away from each other. By so constructing this ventilator it may be fitted to windows of varying widths which is especially desirable when the plates from which the ventilator is constructed are names made of metal. The foraminous fabric used in this form of the invention is shown as screen wire 55 which may be of any suitable or desired mesh.

In the form shown in Fig. 7, foraminous fabric sheets 56 and 57- are shown arranged on a supporting and reinforcing frame 58, being held at their ends in engagement with said frame by the metal strips 6, said frame having openings shown in dotted lines at 59 for the passage of air. This ventilator is applied in the same manner as that shown in Figs. 1 to 4:, and no further description thereof is thought necessary.

From the foregoing description, taken in connection with the accompanying drawings, the advantages of the construction and of the method of operation will be readily apparentto those skilled in the art to which the invention appertains and while l[ have described the principle of operation of the invention together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative and that such changes may be made as are within the scope of the claimed invention.

1 claim The combination with a window frame having vertically movable sash, of guides secured to opposite sides of said frame at its upper and lower ends, said guides each including inwardly opening laterally spaced plates, ventilators having their ends adapted to be inserted between said 'lates, and pliable fingers carried by said p ates to be bent into engagement with said ventilators.

In testimony whereof aflix my signature in presence of two witnesses.
